Evacuees will be housed in the armory for at least 30 days, and possibly as long as 90 days, estimated Cameron Ballantyne, a spokesman for the American Red Cross,.

Events scheduled to take place in that period included at least three Latin concerts, a D.C. Office of Personnel job fair, a convocation held by Friendship Public Charter School and a Wounded Warriors fundraising concert.

Some groups were able to reschedule quickly. The Office of Personnel will hold its job fair at the Washington Hilton on Oct. 5.

Others, such as the Friendship Charter School, are trying to find a new venue.

It is doubtful any events will be relocated to the D.C. Convention Center, which is experiencing one of its busiest seasons.

Lana Ostrander, the center’s deputy director of event management, said it is “very unlikely” the convention center will have room to host any rescheduled events.

The armory continues to provide shelter for about 200 people who lost nearly everything in the floodwaters that submerged New Orleans.
